The domain extent is 40W-40E, 25S-40N
The grid dimensions are 81 points in the west-east direction and 66 points in the north-south direction with 1 degree spacing in the latitude and longitude directions.


For the years 2003, 2004, 2005, 2006 the file naming convention is the same as above with the respective date and time labels.

There are some sample control file(s) and scripts files in the directory for the year 2003. The creation of control files and index files is left for the individual users, using "grib2ctl.pl" and "gribmap" commands.





Monthly averaged Global data files for the year 2000  (avg_2000 directory, after unpacking)
-------------------------------------------------------------------------------------------

     a) Surface Flux file names:   flx200004
                                   flx200005
				   flx200006

                                   flx200009
                                   flx200010

     a) Pressure level file names: pgb200004
                                   pgb200005
				   pgb200006

                                   pgb200010

Control and index files are created for all these files and exist in this directory.

These are 1degree lat-lon global data files with grid dimension (360x181) - the grib format. In addition there are 3hourly data files averaged for the month whose file names end with 00Z, 03Z etc. As also being grib files, control and index files can be created.

The same conventions apply for the datasets for the years 2003 2004, 2005, 2006.
